Description
Technical Field
[0001] The utility model relates to a tentering heat setting machine used in the printing and dyeing industry, in particular to a guide rail in the heat setting machine. Background Art
[0002] The working process of the stenter heat setting machine is as follows: flat cloth feeding → thread expansion → infrared centering → rolling car → disc weft straightening → lower overfeeding → mechanical weft straightening → thread expansion → upper overfeeding → edge stripping → infrared edge detection → upper needle → slurry edge → stentering or heat setting → cold air cooling → edge cutting, edge suction → needle removal → swing-type cloth dropping or small rolling. Two long annular guide rails with open ends are arranged side by side in the stenter heat setting machine, and the two long annular guide rails pass through the drying room of the stenter heat setting machine from front to back. The guide rail located in front of the drying room is usually called the cloth feeding section guide rail, the guide rail located in the drying room is called the setting section guide rail, and the guide rail located behind the drying room is called the cloth outlet section guide rail. The front end of each guide rail is connected to a front mounting seat for installing a driven sprocket, and the end is connected to an end mounting seat for installing a driving sprocket. The driven sprocket on the front mounting seat and the driving sprocket on the end mounting seat are movably connected by a chain, and a needle clip is provided on the chain. During operation, the two ends of the cloth are respectively hung on the needle clips on the adjacent sides between the two guide rails. The distance between the needle clips on the adjacent sides is the width L of the cloth. The driving device drives the two active sprockets to rotate, so that the two chains run in a circular manner in the guide grooves of the corresponding guide rails. As the chains run, the needle clips carry the cloth from front to back through the cloth-inlet guide rail set in front of the drying room, then enter the shaping section guide rail set in the drying room, and finally enter the cloth-outlet guide rail set at the rear of the drying room to remove the cloth and obtain the shaped cloth. For the convenience of description, the side of each guide rail close to the corresponding drying room wall is called the outer side, and the side away from the corresponding drying room wall is called the inner side. The guide rails in the stenter heat setting machine are of two types according to their materials: cast iron guide rails and oil-free steel plate guide rails. Since the chain needs to add lubricating oil when running in the cast iron guide rail, the lubricating oil will volatilize at high temperature after entering the drying room, causing the cloth to turn yellow and affecting the quality of the cloth. However, when the chain runs in the oil-free steel plate guide rail, no lubricating oil needs to be added, which can ensure the quality of the cloth. Each section of the oil-free steel plate guide rail in the currently commonly used stenter heat setting machine includes: two "C"-shaped channel steels located on the inner and outer sides of the guide rail, respectively, and a number of transverse connecting plates are arranged between the two channel steels. The inner and outer ends of each transverse connecting plate are respectively welded to the two channel steels, and the transverse spacing between the two channel steels determines the width of the guide rail. Therefore, when designing a drying room, the factors affecting the width of the drying room include: the transverse spacing and the width L of the cloth. In order to reduce energy consumption, it is necessary to reduce the width of the drying room as much as possible. When the width L of the cloth is determined, the transverse spacing needs to be as small as possible while ensuring the strength of the guide rail.During actual manufacturing, since the two channel steels in the oil-free steel plate guide rail are made of straight steel plates directly folded at the edges, the oil-free steel plate guide rail adopts a front-to-back straight structure. Also, since the cylinder used to tighten the chain needs to be set in the spacing at the front end of the cloth-inlet section guide rail, the lateral spacing between the two channel steels in each guide rail is relatively large, usually 202mm. The cast iron guide rail is cast as one piece during production, and streamlined diameter reduction can be performed in the cloth-inlet section guide rail and the cloth-outlet section guide rail during casting. Therefore, under the premise of ensuring the strength of the cast iron guide rail, the lateral spacing of the shaping section guide rail in the drying room can be greatly reduced, so that the lateral spacing of each guide rail in the drying room is 60mm, thereby achieving the purpose of reducing energy consumption. Therefore, when the width L of the cloth is determined, the width of the drying room of the stenter heat setting machine using oil-free steel plate guide rails is 284 mm wider than that of the stenter heat setting machine using cast iron guide rails, resulting in a greater energy consumption of the stenter heat setting machine using oil-free steel plate guide rails than that of the stenter heat setting machine using cast iron guide rails. Therefore, it is necessary to develop an ultra-narrow oil-free steel plate guide rail, in which the lateral spacing between the channel steels on the inner and outer sides of the shaping section of the ultra-narrow oil-free steel plate guide rail is smaller than the lateral spacing between the channel steels on the inner and outer sides of the shaping section of the traditional oil-free steel plate guide rail, and in which the energy consumption is lower than that of the stenter heat setting machine using the traditional oil-free steel plate guide rail when the width L of the cloth is determined.
